Research on Water Hammer Test of Water Supply Pipeline in Heping County Urban Water Supply Project Considering Mixed State of Water and Gas
To investigate the water hammer leakage characteristics of the water supply pipeline in Heping County,water hammer tests are designed and conducted.An analysis of the influence characteristics of initial operational parameters based on monitoring data is carried out.The study shows that the leakage hole location can alter the temporal evolution characteristics of inlet pressure,but has minimal impact on the evolution of inlet flow.Initial water supply flow operational parameters does not change the temporal characteristics of inlet pressure or leak hole pressure evolution,and the temporal evolution of leak hole pressure exhibits an oscillatory decreasing stage.Initial gas content operational parameters can affect the water-gas mixed state within the pipeline,leading to differences in the temporal evolution of inlet pressure.There is a negative correlation between initial gas content parameters and both inlet pressure and inlet flow level.The study suggests that initial gas content parameters should not exceed 2%,while initial water supply flow should be controlled within safe allowable values.The content of this paper is of reference significance for water hammer leakage and prevention and maintenance of water supply pipeline in water supply engineering.
